Should we do this globally at the Makerules level?
Thanks,

Do we have a simple way to accomplish it? _TIME_SIZE and LFS defines should work for 64-bit ABIs, so we have a global rule to enable it I think it would be better indeed.

Would it be okay to do this for MODULE_NAME=nonlib and MODULE_NAME=ldconfig? Then I think there would be various ways of achieving the desired effect. Thanks, Florian
